iso_checksum (string) - The checksum for the ISO file or virtual hard drive file. The type of
the checksum is specified within the checksum field as a prefix, ex:
"md5:{$checksum}". The type of the checksum can also be omitted and
Packer will try to infer it based on string length. Valid values are
"none", "{$checksum}", "md5:{$checksum}", "sha1:{$checksum}",
"sha256:{$checksum}", "sha512:{$checksum}" or "file:{$path}". Here is a
list of valid checksum values:
iso_url (string) - A URL to the ISO containing the installation image or virtual hard drive
(VHD or VHDX) file to clone.
